Uninterrupted Motive Power Supply System carries out the function of providing power to load in case of blackout while at the same time does not require to be oversized in its rating. The System is available up to 1500 Kw, 50/ 60 Hz, low tension or high tension voltages. The System ensures power backup to 3 ph motor loads with double conversion of power and the batteries are also charged. The System has the feature that in case of power failure, the charged battery continues to feed the motor through controlled inverter without any interruption to the load and the backup time is decided by the load and ah capacity of the battery. The System is an efficient way to support induction motor loads during total black out and has static switch that ensures changeover of load to battery during black out. The Uninterrupted Motive Power Supply System has various protections such as phase to phase short circuit, motor overload, single phase at motor end, under voltage at input, over temperature in the motor, deep discharge of the battery, battery overcharge protection, phase to ground short circuit, single phase at input of the system, over temperature in the inverter system, over temperature of the transformers and battery reverse polarity protection.
